I change my strings every 2 nights, whether I need to or not, as it were. The guitar in question, a limited edition Washburn, (which, incidentally, has been called a 'sound engineer's dream')I have had re-customised to suit the '60s to 17s that I put on it (It is tuned to DAGDAD permanently...)
But my point is that this stuff HAS changed my breakage rate. The angle that my strings hit the bridge at, is <5° (thanks to the tailpiece that the strings emanate from), and the sound is deep and full-bodied. Of course the Phosphor Bronze wound will bugger up the bridge eventually, and of course, as every chord that is played on the thing is some variation of a 'power chord' in the first place, the strings will eventually give way (hence the reason for my Quixotish quest in the first place...) When I first bought the guitar, it was the bridge that used to break (I kid you not!), and I went around chasing my tail for a couple of months, switching to bone bridges, then plastic again, then lighter strings (I even tried Nickel [spit spit!] strings for a while). Then I met a luthier who was clever and innovative (who has since moved to Japan). Ones I have been talking to since, just scratch their heads, and tell me things I have been hearing for 10 years, that have been tried and tested, before the idea would get eventually knocked on the head.
I have had to take other precautions in the meantime. When your'e playing a set of reels, for example, it would not be unusual for instruments to drop out and come back in again. I can whack a broken string off, and a new one on and tuned in 20 seconds or less. If I'm doing a solo gig, I can switch guitars and do something else, if I don't want to 'talk over' the string change.
All of this is no more! Well, almost no more.
Seriously folks, I have had the head scratched off myself for years, trying to have my cake and being able to eat it as well (as far as the guitar is concerned), and not being one to be easily impressed, I do actually have to take my hat off to the stuff.
